Hartz UltraGuard Pro Flea and Tick Drops are
placed at the skin level on the dog's back in between the shoulder blades to the base of his tail to kill fleas, ticks and mosquitoes on contact for up to 30 days.
The
place where the tick attaches may or may not be painful and there may be
skin swelling — It is distinguished from other
skin swellings and growths because close scrutiny can reveal the tick's legs
at the
level of the
skin.
